May 2 1933. v. CASTIAUX DEVICE FOR UNDULATION OF HAIR Filed March 16, 1952 Patented May 2, 1933 messes PATENT VICTOR CAST'IAUX, OF BOBIGNY, FRANCE DEVICE FOR UNIDULATION OF HAIR Application filed March 16, 1932, Serial No. 599,312, and in France March 17, 1931.

' The present invention relates to a device for undulati-on of hair.

This device permits of fastening surely the lock of hair to be undulated, and to wind it automatically around the support. This op eration is performed in quite an easy way by the simple rotation of a protecting cylinder introduced with the lock-support into an electric heating body.

The particularities of the device reside in the hair winding element. in the element for retaining the lock, and in the means for'the liX- ation of the lock-support in the heating body.

Finally. in the device according to the invention. the hair undergoes the temperature created by the heating body without entering in any contact with this body. the hair being contained in a chamber, where air alone 20 transmits the heat to the hair.

The invention will be better understood in the course of the following description relating to the drawing appended.

Fig. 6 shows the arrangement of the locksupport within the heating body in a lateral 35 view Fig. 7 is a corresponding front view. and

8 is a plan view of a device fixing the lock-support in the heating body.

The device according: to the invention comprises a lock-support 1 (Fig. 1) consisting of a rod of aluminium. duraluminum or of another metal and fixed to a disc 2 provided with an inner recess 1 for the passage of a fork 3. This fork mav be equipped in case of emergencv with means for its retaini in position. such as cams. fixing pins or the like. The disc 2 is provided with a hole 4 and with a slit 5 for the introduction of the hair to be undulated. in the sense of the arrow 7 On the disc is provided a circular flange 6 interrupted at the entry of the slit 5 and provided with a slight depression at 6 The lock-support may be headed by a bush 7 pierced at the bottom for the passage of the support, and provided (Fig. 2) with a slit 8 situated in the sense of a generatrix and abutting into a sting 9 projecting below a recess 10 provided at the bottom-part of the bush in the shape of a slope.

In the interior of the bush 7 is fixed a spring-blade 11 formed in such manner that its free extremity applies against the lock-support (Figs. 2 and 5) this spring is eventually provided with suitable slits in order to 1shape itself in a better way on the lock of lair.

After placing the bush 7 over the lock-support 1, the sting 9 rubs against the disc 2 on rotating the bush.

This permits of obtaining the winding of the lock of hair in the following manner:

The bush 7 is separated from the lock-sup port 1 and the lock of hair is introduced into the hole 4 of the disc 2 through the slit 5, I as indicated in Fig. 3. The fixation of the 7 lock in the disc is obtained by means of the fork 3. This fork is introduced into the cavity or mortise 1.. of the disc 2 (Fig. 4c) and pushed until the lock is fixed between the border of the hole 4 and the bottom of the 8 fork 3.

In this position the fork is fixed by means of an eccentric cam 12 controlled by a finger 13 and acting upon the branches of the fork, r viz. spreading them apart and quenching '85 them against the walls of the mortise 1 of the disc 1.

Now the lock of hair is fixed surely in the apparatus. Thereupon the bush or sleeve 7- is shifted over the lock-support, the extremity of the lock having been previously laid down toward the exterior.

On rotating the sleeve 7 the sting 9 slips below the hair (Fig. 3) so that the same is guided, at one part by the slope 6 and at the other part by the slope 10, into the slit 8, at which rotary movement of the sleeve 7 the hair winds itself around the support 1 and is pressed against the latter by the spring-blade 11. In this way the hair is The support and the sleeve are introduced thereupon into the heating body 14 (Fig. 6) enclosing an electric resistance 15 fed by means of plug contact 16 attached to the upper part of the body. In the interior or on the exterior of the heating body an interruptor may be provided.

Between the disc 2 and the border of the heating body an elastic washer 17 is provided for ensuring the tightness of the apparatus and for permitting of an easier working of the means for fixing the lock-support in the heating body in the manner described later on.

The lock-support traverses the heating body and is in its upper part projecting outwardly from this body, shaped in the manner of a whistle, at 18.

To the heating body is articulated a stirrup 19 provided with an arresting bridge 20 abutting against the support at the side opposite to the whistle-like part. To the. stirrup 19 is also articulated a spur 21 provided with a handle 22 of a material insulating heat. The stirrup 19 pivots around pivots 23 Whilst the spur 21 pivots 011 the stirrup around pivots 24: (Figs. 6 to 8).

After insertion of the lock-support into the heating body, the spur 21 being at that time in the position shown in Fig. 6, it suflices for the immobilization of the support within the heating body to raise the handle 22 so that its spur or tooth 21 engages below the, or into the, recess 18 and that the line passing through the axles 23, 24 moves to the side opposite to the vertical axis of the support, viz. the position indicated by the dotted line in Fig. 6.

In this position the spur 21 sticks to the recess 18 so that the release of the spur is possible only by exertion of a pressure upon the handle, this release freeing the support. This movement of the spur is rendered possible owing to the elastic washer 17.

Owing to the electric current traversing the body 14 the hair undergoes heating Without danger of being burnt no contact existing between the heating body, and air only serving for transmission of heat. Furthermore, insulating pieces can be intercalated in order to avoid all electric contact of the locksupport with the heating body 1 1, 15.

It is obvious that the apparatus described and represented merely in the way of an example permits of manifold modifications both with regard to the general arrangement and to the details without deviating from the scope of the main inventional idea. The fixing means for the lock-support such as the stirrup 19 with its arresting bridge 20, for example, can be entirely dispensed with,

Without modifying the essential features of the invention and without altering its workmg. 7

What I claim, is:

1. In a device for the undulation of hair, an axle to serve as hair-support, a disc, to which said axle is attached, a hole in said disc, a slit in said disc, leading tosaid hole, a sliding fork entering the slit and adapted to straddle the lock of hair in the hole and pinch said lock at the bottom of the hole to fasten it in the hole, to fix the lock of hair introduced into said hole, a sleeve rotatable on the disc and having a longitudinal slot to receive the lock of hair to ensure winding of said lock around said axle, and means to heat the lock.

2. In a'd-evice for the undulation of hair, an axle to serve as hair support, a disc to support said axle, a hole in said disc for the introduction of a lock of hair, a sliding fork coacting with the edge of the hole to fix the hair, a sleeve, a longitudinal slit in the same, a sting at the bottom part ofthe slit, a slope on said disc, for winding the hair around said axle, and means to heat the lock.

3. In a device for the undulation of hair, an axle to serve as hair support, a disc to support said axle, a hole in said disc for the introduction of a lock of hair, means to fix the hair in said hole, a sleeve, a longitudinal slit in the same, a sting at the bottom part of the slit, for raising the lock of hair, a slope on the disc to coact with said sting to Wind the hair around the said axle, a spring-blade fixed to said sleeve, within the same, to flatten the hair and to smooth. the same so as to obtain a regularly wound hair-layer on the axle, and means to heat the lock of hair.

4. In a device for the undulation of hair, an axle to serve as hair-support, a disc to support said axle, a hole in said disc for the introduction of a lock of hair, means to fix said lock to said disc, a sleeve to take along said lock and to wind it around said axle, a spring blade fixed inwardly to said sleeve, to flatten and to smooth the hair wound around said axle, slits in said spring-blade to allow of their better shaping upon the lock of hair, means to heat the wound lock of hair, and means to secure the fixation of said axle during the rotation of said sleeve.
